Front

What is the maximum number of electrons possible in the valence layer of most elements?

Back

8

Front

What is the Bohr model of an atom?

Back

A diagram that represents the atom with electrons in defined orbits around the nucleus, similar to planets orbiting the sun.

Front

How do you find the number of neutrons in an atom?

Back

Atomic mass - Atomic number.

Front

Which element is in the same family as carbon?

Back

Silicon.

Front

What is the atomic number of an element?

Back

The number of protons in the nucleus of an atom.

Front

What is the significance of the periodic table?

Back

It organizes elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the difference between atomic mass and atomic number?

Back

Atomic mass is the weighted average mass of an element's isotopes, while atomic number is the number of protons in the nucleus.

Front

What is an isotope?

Back

Atoms of the same element that have the same number of protons but different numbers of neutrons.

Front

What is a chemical family or group in the periodic table?

Back

A column of elements that have similar chemical properties due to having the same number of valence electrons.
